Reproducibility assessment of biventricular strain derived from Long-Axis feature tracking in travelling Volunteers - A study in the Berlin research network for cardiovascular magnetic resonance (BER-CMR).

ABSTRACT:

Purpose

To evaluate the reproducibility of biventricular global longitudinal strain (GLS) assessment using cardiovascular magnetic resonance in a multicenter study of travelling volunteers.

Methods

Twenty travelling volunteers were prospectively scanned at four sites with same-vendor scanners at 3.0T (sites I, II, III) and 1.5T (site IV). Cine imaging in three long-axis views was performed using a segmented balanced steady-state free precession sequence with 30 cardiac phases except site II with 25 phases.

Results

Imaging and post-processing were carried out successfully for 18 volunteers in a core lab setting. Pairwise comparisons revealed significant differences in left ventricular (LV) GLS between sites I and II (p < 0.001) and sites II and IV (p = 0.013), as well
